Circuit Explanation: The BG2C is a basic two channel gate driver designed around the recommended
application circuits for the Powerex VLA507 and VLA513 hybrid IGBT gate drivers in combination with either
VLA106-15242 or VLA106-24242 isolated DC to DC converters.
A functional block diagram of the VLA507/513 hybrid gate drivers is shown for reference in Figure 1.
These gate drivers are optimized for use with Powerex NFH series and CM**DUS-12F IGBT modules. The
drivers use a high speed open collector type opto-coupler to provide 2500VRMS isolation of control signals. The
output stage is designed to provide high current gate drive with the appropriate on and off-state bias voltages for
large IGBT modules. For additional detailed information on the characteristics and operation of these gate
drivers please refer to the individual device data sheets.
Figure 2 shows a block diagram of the VLA106-15242 and VLA106-24242 hybrid DC to DC converters.
These two devices are identical except that VLA106-15242 is designed to operate from a 15 VDC input and the
VLA106-24242 is designed to operate from a 24 VDC input. These DC to DC converters use a transformer to
provide 2500VRMS isolation for gate drive power. The converter’s regulated 24VDC output is split using a
resistor and zener diode to provide +15.8V and -8.2V for the hybrid gate driver. For additional detailed
information on the operation of the hybrid DC to DC converters please see the individual device data sheets.
